  • the disperse dyes are water-insoluble to sparingly soluble dyes of various classes, for example nitro dyes, amino ketone dyes, ketone imine dyes, methine dyes, nitrodiphenyl dyes, quinoline dyes and in particular anthraquinone or azo dyes such as monoazo or disazo dyes. It is also possible to use mixtures of different disperse dyes.
  • aqueous preparation which contains the dye (or dye mixtures) which is insoluble to poorly soluble in water.
  • Suitable aqueous preparations of this type are, in particular, those described in DE-A-2,850,482.

  • the printing paste is applied over the entire surface or in places directly to the fiber material
  • printing machines of a conventional type e.g. Gravure printing, rotary screen printing and flat film printing machines can be used appropriately.
  • the fiber material is dried at temperatures up to 150 ° C., preferably 80 ° to 120 ° C.
  • the prints are also finished in the usual way by rinsing with water and can optionally be cleaned by additional cleaning in an alkaline medium under reductive conditions, e.g. be made with sodium dithionite. In the latter case, the printing stains are again rinsed and dried.
  • the present method is also suitable for transfer printing.
  • the printing paste is applied over the entire surface, preferably in the form of a pattern, to the intermediate carrier, printing presses of conventional design, e.g. Rotary screen printing and gravure printing machines can be used appropriately.
  • the intermediate carrier used in the transfer printing process is expediently a flexible, preferably spatially stable tape, a strip or a film with a smooth surface.
  • the intermediate carrier should be heat-stable and inert, ie should have no affinity for the various components of the printing paste. It can consist of various materials, such as metal, such as an aluminum or steel foil, plastic, paper or a textile fabric, which can optionally be coated with a film of vinyl resin, ethyl cellulose or polyurethane resin. For cost reasons, primarily paper webs are used.
  • the printed intermediate carrier is dried at about 80 to 150 ° C., in particular 80 to 120 ° C., for about 5 to 20 seconds.
  • the actual transfer printing is carried out discontinuously on a press or continuously on a conventional thermal printing system at 160 to 250 ° C., in particular 190 to 220 ° C.
  • the contact time is dependent on the set temperature and is between 20 and 60, preferably 30 and 45 seconds at 230 ° C. and is carried out using pressure, the dye being transferred from the intermediate carrier to the fiber material.
  • the printed fiber material is separated from the intermediate carrier.
  • no after-treatment is required, i.e. generally neither steaming to fix the dye, nor washing to improve fastness properties.
  • the present process can be used to produce vivid, true-to-color and rub-fast prints with good white fond of the goods, which are characterized by high lightfastness of the prints and stability of the fiber material.
  • a strong, pattern-like print is obtained on the polyester fabric on a white background with good levelness, good fastness properties and with sharp contours.
